WINDOW-SCREEN.

Specification of Letters Patent.

Application filed October 24, 1913, Serial No. 296,988. Renewed September 9, 1916. Serial N 0. 119,279.

To all whom it may concern:

Be it known that I, FRANK L. RIGKER, of Portland, in the county of Cumberland and State of Maine, have invented certain new and useful Improvements in Window- Screens, of which the following is a specification.

My invention relates to window screens and particularly to screens adapted to be used on the so-called Austral or balance sash windows. These windows are illustrated in United States Letters Patent No. 821,510 issued May 22, 1906, and they consist of an upper and lower sash with the usual meeting rails, the lower portion of the upper sash and the upper portion of the lower sash being pivoted at a point a short distance'from their ends to the ends of a pair of centrally pivoted balance levers which are in turn pivoted to the parting strip. The upper end of the upper sash and the lower end of the lower sash are pivoted in a vertical slot in the casing which allows them to move vertically. As a result of this construction the upper end of'the lower sash may be swung inwardly and the lower-end of the upper sash outwardly at the same time opening a space at the top and bottom of the window. These windows which have gone into extensive use have always been diflicult to screen on account of their peculiar construction. V

The object of my invention is to devise a screen which will perfectly close the window opening while allowing the sash to be freely opened and closed, which may be removed without leaving an opening between the meeting rails of the sash to be filled in by a removable filling piece and which may be freely opened while in place and without being removed. These objects I accomplish by means of the window screen hereinafter described and claimed.

My invention may best be understood by reference to the accompanying drawingin which is shown a window of the Austral type screened in accordance with my present invention.

In the drawing, Figure 1 is a central vertical section taken through the window, Fig. 2 is a partial elevation looking from the inside, Fig. 3 is a detail elevation showing the hub of the balance lever and its pivot block with the filling piece in section, Fig. 4 is a section taken on the line at m of Fig. 3, Fig.

' 5 is apartial section on the line w wof Fig.

1, Fig. 6 is a perspective view of oneend of the'filling piece, and Fig. 7 is a vertical section taken on the line as so of Fig. 6. Fig. 8 is a modification in which the meeting rails of the sashes'close over the filling piece. to

make a closed joint.

Referring to Figs. l-7 of the drawing, crep'resents the window casing, b the partmg strip, c-the upper sash, d the lower sash, c and d the meeting rails of the two sashes.

.c is one of the balance levers pivoted by means of a pivot e in a pivot block 6 secured to the parting strip 6.

The pivot block is provided with suitable screw holes near its upper and lowerends and is secured to the parting strip by screws passing. through these holes. The upper end of the upper sash and the lower end of the'lower sash are connected with the easing by means of a verticalslot and pin connection to permit vertical movement of the sashes as indicated by dotted lines in Fig. 1. The lever has a hub or enlargement in the center and the ends are pivoted to the sash by suitable connections. When screens are to be used the meeting rails are separated by an intervening space or opening.

The above are the parts of the Austral window as commonly constructed and need no further description. For the purpose of screening this window, I provide an upper screen f which fits the casing above the sash d and rests against the inner. face of the parting strip opposite the sash 0 and a lower screen 9 which fits against the outer face of the parting strip opposite the sash d.

The screen 7 is pivoted by suitable means to the casing at or near its upper end. As here shown, I make use of pivoting screws f inserted in the sides of the casing and passing through clips and the screen 9 is pivoted'in like manner preferably at its up- The space between the adjacent ends of metal. Thesection h is bent to form aver tical flange h and an inclined flange h The vertical flange it extends vertically up ward on one side of the opening between th meeting rails, projecting above the rail d far enough to make a fly proof joint withf the lower end of the screen f. The loweri section '2' is the complement of the upper sec-g character described, having an upper and a tion, having a vertical flange 11 which extends downwardly along the inner face of the rail 0 and extending far enough belowsaid railto make a tight joint with the upper end of the screen 9. i The inclined flange i fits against the under side of the inclined flange h of the section h,the two abutting to form a tight joint which may include a gasket to make thejoint impervious to rain,

snow, dust or air. Means are provided whereby the filling piece may be secured to the parting strips at their ends, making use of the screw holes of the pivot blocks and bringing the vertical portions flush with the faces of the parting strips.

Asshown, the ends of the inclined flanges z' and k of the two sections 72. and z are cut away to fit closely around the hub of the balance lever e and'the vertical flanges h, and z" are bent at right angles to form two fasteningflanges k and i thesetwo flanges being vertically in line with each other. Each is provided witha screw hole which is in the exact position to fit one of the screw holes in the pivot block (see Figs. 3'

and 4) and theyare fastened in place by the same screws which hold the pivot block.

It will be seen that by releasing the dogs f the screen f may be swung inwardly at the bottom, making an opening as large as desired. In the same manner the screen 9 may be opened by swinging the bottom out. wardly. Thefilling' piece having'been once put in place need not be removed when the screens are taken out but may be left in place indefinitely. a

In the winter the screens may be easily removedand double windows put in their place without disturbing the filling piece.

The screens and filling piece are here shown as being made of metal but they may be constructed if desired of wood and other changes may be made in the construction herein shown without departing from my inventionas defined in the claims In Fig; 8 I have shown a modification in which the meeting rails of the sashes close over the filling piece to make a closed joint doing away with the recess between the rails. Referring to the Fig. 8 d and c are the meeting rails. and h and i the upper and lower sections of'the filling pieces. The

upper section is bent to form a vertical lip 1 to connect with the screen f, thence it makes ahorizontal'ben'd 2 to about the center of the parting strip,sthence downward s secured to the flange 4 by a bolt 6 or 1.
